WeatherHawk 89498 ET Weather Station, Wired

WeatherHawk ET Weather Station, Wired

Direct connect, serial cable included.

Designed for easy installation and use! This industrial grade, fully assembled weather station measures wind speed and direction, air temperature, relative humidity, barometric pressure, solar radiation, rainfall, and ETo (evapotranspiration). The included WeatherHawk XP/X software allows for sophisticated data management and operates on PC-XP or Macintosh OS-X. Weather station, solar panel kit (for use in lieu of a DC power supply), and software included with both models.
